DESCRIPTION
Select this option to turn on redundancy between a pair of NXC-8160s. You can
deploy one NXC-8160 as the main device and the other as the standby one.
When you have two NXC-8160s in the network, select Main to have this NXC-8160
act as the active WLAN controller and set another NXC-8160 as the backup WLAN
controller. Otherwise, select Standby and this NXC-8160 will function as a backup.
The backup WLAN controller periodically tests the connections to the main WLAN
controller and the referenced host. If the connection to the main WLAN controller is
down and the connection to the referenced host is up, the backup WLAN controller
becomes active automatically.
If the main WLAN controller fails, wireless clients can automatically connect to the
backup WLAN controller.
Enter the IP address of this NXC-8160 WLAN controller.
Enter the IP address of a reliable nearby network device to have the NXC-8160
periodicially ping that address to test the integrity of its network connection.
The NXC-8160 tests the connection by sending a ping to the address in the
Reference IP field every X number of milliseconds.
Select a number of milliseconds to set as the time interval between checks. Allow
more time if your destination IP address handles lots of traffic.
Select the number of the lost packets that can be allowed before the the connection
is considered "down" (not connected).
Click Save to save your settings.
